Bug description:
  In newer kernels (>= 3.6) the nfs modules were split up and we have to
  include nfsv3, nfsv4, and nfs_acl now. This was already fixed in
  raring in initramfs-tools 0.103ubuntu0.3, but precise with lts-raring
  kernel is still affected.

  Marking those modules for inclusion even on older kernels where they
  don't exist seems to be safe. initramfs-tools doesn't complain.

  [Impact]

  We have to manually configure the initramfs to include nfsv3/nfsv4
  modules before we can boot from NFS.

  It is not possible to boot the 12.04.3 LiveCD from NFS (regression
  compared to .0/.1/.2).

  [Test Case]

  With linux-image-generic-lts-raring installed, list the contents of
  the initramfs and check for nfs related modules:

  gunzip -c /boot/initrd.img-3.8.0-* | cpio -t | grep nfs

  nfsv3.ko and nfsv4.ko should both be present.

  [Regression Potential]

  Minimal. The change adds three extra modules to the initramfs, and
  they are ignored on kernels that don't have them.
